Haha, probably you could modify it. But then you'll need a more powerful laser to kill human sized animals, or humans. And since those are a little bit to large to be mobile, and require too many power, you won't be able to modify it in that specific way

Though, you could try to make it remote controlled and with a webcam, so you can control it with a laptop or something.
